BUNG AND BUSHING.

SPECIFICATION forming part of Letters Patent No. 368,139, dated August9, 1887.

Application flled June 6, 1887.

To all whom it may concern.-

Be it known that I, OSCAR EISENHUTH, a citizen of the United States,residing at De troit in the county of \Vayne and State ofMichigan,haveinvented certain new and useful Improvements in CombinedBungs and Bushings; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

My invention is designed for closing the tilling or bung-holes ofbarrels and kegs, being especially designed forbeer-kegs;anclitconsistsin the construction and combination of parts forming a metallic bung andbushing, as here- 2o inafter set forth, and pointed out particularly inthe claim.

In the accompanying drawings, forming a part of this specification,Figure 1 is an isometrical view of the device embodying my invention,showing the handle for locking the bung removed. Fig. 2 is a. section inelevation, taken on the dotted line a: w of Fig. 1, showing also asection of a keg. Fig. 3 is a perspective of the bushing-ring (lookinginto 3c the upper end) having the bung removed.

In the drawings, B designates the metal ring or bushing, having on itsouter-periphery the screw-threaded surface S. The upper or outer end hasthe flange F, with angular sur- 3 5 face a on its periphery to receive awrench to enable the screwing of the bushingring into the hole of a keg.The periphery of the flange is octagonal in form. An annular chamber, R,is formed in the upper half of the bushing extending down to the annular:flange f, and J is a smaller chamber passing through the bushing.

I form in the flange F, on opposite sides, the vertical channels Z Z,communicating with the inclined channels Z havim near the lower end inthe upper wall a notch or recess, 6. (See Fig. 3.)

Cis a metal cap having an oval top, XV.

Crossing said top is a channel, (1, having inclined or undercut sides '66. (See Figs. 1 and 2.) The upper portion of the cap is made to registerwith and pass freely into the chamber R of the bushing-ring, (see Fig.2,) and has on its outer periphery the annular flange or shoulder 0. Thecap is hollow, as shown at E, having on its lower end the cylinder Y,which freely passes through the chamber J of the bushing B.

I locate on the outer periphery of the bung or cap C, and at rightangles to the channel d, the lugs or pins VV, which have a slightprojection. (See Fig. 2.) The projection of each pin is equal to thedepth of the channels Z Z, and the pins are adapted to pass freely intosaid channels, engaging therewith.

D is a handle having the shoulders i i and stem K, with beveled edges an. The stem is adapted to be slid into the channel (I of the cap, forthe purpose of turning said cap or bung, and to lift it out of thebushing when unlocked, as hereinafter specified.

The parts are to be operated as follows: To insert the bushing into thehole of the keg H,

a wrench is applied to the flange F. Turning the wrench causes thebushing to enter the 7 keg. hen sulflciently secured, a leather orflexible washer, P, is placed on the annular flange f, the bung C isplaced into the bushing, its lugs or pins V V entering the verticalchannels Z Z of the bushing. Then the arm K of the handle is passed intothe channel d of the bung or cap C, and by swinging said handle aroundin the direction of the arrow in Fig. 1 the cap is caused to revolve,forcing the lugs V along the inclined channels Z, thus drawing theannular shoulder O onto the washer P and closing the parts. The cap isto be revolved until the pins V meet the notches 0, when the pressure ofthe washer P will force said pins slightly upward into the notches, 0thus preventing the cap or hung from working loose. All of this is shownin Figs. 2 and 3. Vhen the cap is locked, the handle D is removed. Tounlock said parts the handle is inserted into the cap 0, and by givingaslight 5 jerk on the handle (in an opposite direction to that indicatedby the arrow in Fig. 1) the pins V Vwill move out of the notches alongthe channels Z until they enter the vertical channels Z Z, when liftingon the handle the I00 cap will be removed from the bushing.

Having thus set forth my invention, what I claim as new, and desire tosecure by Letters I said cap, and the packing located between the :0
